18. Definitions of SDI
Executive Order of US (1994) National Spatial Data Infrastructure (NSDI) means the technology, policies, standards and human resources necessary to acquire, process, store, distribute, and improve utilization of geospatial data.

19. Definitions of SDI
Wytzisk and Sliwinski (2004) A SDI can be understood as a multi-leveled, scalable, and adaptable collection of technical and human services, which are interconnected across system, organizational and administrative boundaries via standardized interfaces. Those services enable users from different application domains to participate in value chains by gaining seamless access to spatial information and geo-processing resources.

20. Definitions of SDI
Utility view: SDI is a network facility for accessing and sharing spatial data.
Component view: spatial data, standards, policies, technology and people
Utility and goal: a network facility for supporting spatial issues in society accessing and sharing spatial data

21. Characteristics SDI Holistic concept
Complex system (see Paper Grus et al. in Reader)
Serving the organization/society not only a particular application
5 components and interaction between components

22. Question
What are the main reasons to initiate SDI development?
